determine ability of patient to recognize color;
most common is Ishihara test for red-green color
blindness

Process of injecting dye (fluorescein) to observe
movement of blood and detect lesions in macular
area of the retina; used to determine if there is
detachment of the retina

through the pupil

ophthalmoscope

Perfectly

Examination of interior of the eves using instrument called ophthalmoscope: pupil is dilated in order to see cornea, lens, and retina: used to identity abnormalities in blood vessels of the eve and some systemic diseases

ophthalmoscopy

Instrument used to measure how well the eye is
able to focus images clearly on the retina

optometer

Process of visually examining conjunctiva, cornea, iris, and lens of the eye

slit lamp microscopy

Perfectly

Chart used for testing distance vision named for Dutch ophthalmologist Herman Snellen; contains letters of varying sizes and is administered from a distance of 20 feet; person who can read at 20 feet what average person can read at this distance is said to have 20/20 vision

Snellen chart

Measurement of intraocular pressure of the eye using tonometer to check for condition of glaucoma; generally part of normal eye exam for adults

tonometry

Measurement of sharpness of patient's vision; usually, Snellen chart is used for this test in which patient identifies letters from a distance of 20 feet

visual acuity (VA) test

Surgical removal of all or part the eyelid

blepharectomy

Surgical repair of the eyelid; common plastic surgery to correct blepharoptosis

blepharoplasty

Surgical repair of the conjunctiva

conjunctivoplasty

Surgical fixation of the retina by using extreme cold

cryopexy

Surgical removal of an eyeball

enucleation

Use of artificial lens to replace the lens removed during cataract surgery

intraocular lens (lOL) implant

Surgical removal of a small portion of the iris

iridectomy

To cut into iris and sclera

iridosclerotomy

Surgical repair of the cornea is simple translation of this term utilized to mean corneal transplant

keratoplasty

Correction of myopia using laser surgery to remove corneal tissue

laser-assisted in situ keratomileusis

Use of laser beam to destroy very small precise areas of the retina; may be used to treat retinal detachment or macular degeneration

laser photocoagulation

Use of high-frequency sound waves to emulsify (liquefy) a lens with a cataract, which is then aspirated (removed by suction) with a needle

phacoemulsification

Surgical use of laser to reshape the cornea and correct errors of refraction

photorefractive keratectomy

Surgical injection of gas bubble into the eye and positioning the head so that bubble presses against area of detached retina

pneumatic retinopexy

Spokelike incisions around the cornea that result in it becoming flatter; surgical treatment for myopia

radial keratotomy (RK)

Surgical fixation of the retina; one treatment for a detaching retina

retinopexy

Placing a band of silicone around outside of the sclera that stabilizes a detaching retina

scleral buckling

To cut into the sclera

sclerotomy

Incision into the eye muscles in order to correct strabismus

strabotomy

tympanic

Pertaining to vestibule

vestibular

Graphic record that illustrates results of audiometry

audiogram

Instrument to measure hearing

audiometer

Test of hearing ability by determining lowest and highest intensity (decibels) and frequencies (hertz) that person can distinguish; patient may sit in soundproof booth and receive sounds through earphones as technician decreases sound or lowers tones

audiometry

Measures intensity or loudness of a sound; zero decibels is quietest sound measured and 120 dB is loudest sound commonly measured

decibel (dB)

Measurement of frequency or pitch of sound; lowest pitch on audiogram is 250 Hz; mea- surement can go as high as 8000 Hz, which is highest pitch measured

hertz (Hz)

Surgical puncture of the eardrum), with removal of fluid and pus from the middle ear to eliminate persistent ear infection and excessive pressure on the tympanic membrane: pressure equalizing tube is placed in the tympanic membrane to allow for drainage of middle ear cavity: tube typically falls out on its own

myringotomy

Surgical repair of the external ear

otoplasty

Small tube surgically placed in child's eardrum to assist in drainage of trapped fluid and to equalize pressure between middle ear cavity and atmosphere

pressure equalizing tube

To cut into the auditory tube

salpingotomy

Removal of the stapes bone to treat otosclerosis (hardening of the bone); a prosthesis or artificial stapes may be implanted

stapedectomy

Surgical removal of the tympanic membrane

tympanectomy

Surgical repair of the tympanic membrane

tympanoplasty

To cut into the tympanic membrane
